Question

On Friday, a local hamburger shop sold a combined total of 252

hamburgers and cheeseburgers. The number of cheeseburgers sold was two times the number of hamburgers sold. How many hamburgers were sold on Friday

Answer 1

84 hamburgers

Explanation:

We are given that a total of 252 hamburgers and cheeseburgers were sold at a shop.

Given that the number of cheeseburgers sold was two times the number of hamburgers sold, we are to find the number of hamburgers sold.

Assuming
`x` to be the number of hamburgers and
`y` yo be the number of cheeseburgers:

`x+y=252`

Cheeseburgers = 2 (hamburgers)

`y=2x`

`x+2x=252`

`3x=252`

`x=84`

Therefore, 84 hamburgers were sold on Friday.

Answer 2

Answer: 84 hamburgers were sold on Friday.

Explanation:

Let be "x" the number of hamburguers sold on Friday.

Knowing that the number of cheeseburgers sold was two times the number of hamburgers sold, this can be represented with:

`y=2x`

Then, we can write the following expression:

`x+y=252`

Substituting
`y=2x`:

`x+2x=252`

And finally solving for x:

`3x=252\\\\x=(252)/(3)\\\\x=84`

So, 84 hamburgers were sold on Friday.
